What are the vaccines to prevent cervical cancer?

The main vaccines to prevent cervical cancer include bivalent HPV vaccine, quadrivalent HPV vaccine and nine-valent HPV vaccine. These vaccines mainly reduce the probability of cervical cancer by preventing human papillomavirus infection. It is recommended to choose the appropriate vaccine type based on age and needs.

1. Bivalent HPV vaccine

The bivalent HPV vaccine mainly prevents infection by HPV16 and HPV18 viruses, which are closely related to the occurrence of cervical cancer. The vaccine is suitable for women aged 9-45 and can significantly reduce the risk of cervical cancer and precancerous lesions after vaccination. The vaccination schedule is usually one injection each at 0, 1, and 6 months. Minor reactions such as local redness and swelling or low-grade fever may occur after vaccination.

2. Quadrivalent HPV vaccine

The quadrivalent HPV vaccine adds protection against HPV6 and HPV11, which mainly cause genital warts. This vaccine is suitable for women aged 20-45, and the vaccination procedure is the same as the bivalent vaccine. In addition to preventing cervical cancer, it can also reduce the occurrence of genital warts. Reactions such as pain at the injection site or headache may occur after vaccination.

3. Nine-valent HPV vaccine

The nine-valent HPV vaccine covers seven high-risk types of HPV16, 18, 31, 33, 45, 52, and 58 and two low-risk types of HPV6 and 11, with a wider prevention scope. The vaccine is suitable for women aged 16-26, and the vaccination schedule is 0, 2, and 6 months. The nine-valent vaccine has a preventive effect of more than 90% on cervical cancer and is currently the most comprehensive HPV vaccine covering virus types.

4. Precautions for vaccination

A health assessment is required before receiving the HPV vaccine. People who are allergic to vaccine components should not receive the vaccine. Pregnant women should postpone vaccination, and breastfeeding women should choose carefully. You need to stay under observation for 30 minutes after vaccination. If you have a severe allergic reaction, you need to seek medical treatment promptly. The protection period of the vaccine can reach more than 10 years, but regular cervical cancer screening is still required after vaccination.

5. Other preventive measures

In addition to vaccination, prevention of cervical cancer also requires avoiding multiple sexual partners, using condoms, and quitting smoking. Regular cervical cytology and high-risk HPV testing can detect lesions early. Maintaining a healthy lifestyle and enhancing immunity can also help reduce the risk of cervical cancer.

The HPV vaccine is an effective way to prevent cervical cancer, but you still need to maintain good living habits and regular screening after vaccination. It is recommended that women of appropriate age choose the appropriate vaccine type under the guidance of a doctor and complete the full course of vaccination. In daily life, you should pay attention to the cleanliness of the perineum, avoid unclean sex, eat a balanced diet and exercise appropriately to enhance your physical fitness. If symptoms such as abnormal vaginal bleeding or increased secretions occur, you should seek medical examination in time.
